Description

I have been mad enough to try this from my Bortle 5+ big city suburbs location. With RASA11 quite long FL and OSC this all together made it a very tough target for me. I like the result but from 40+ hours I was expecting much easier processing and super smooth result - which is not. Here resized to 75% of the original APS-C sensor. I bet under good sky this would be 1/4 of the time required - and I must some time try, but I have never yet moved from my background to the better location up till now.
